Dedicated General-Purpose ECSs

Overview

C4 ECSs use second-generation Intel® Xeon® Scalable processors and high-speed intelligent NICs to offer powerful and stable computing performance, and ultra-high network bandwidth and PPS.

C3 ECSs are developed based on KVM virtualization, use Intel® Xeon® Scalable processors and Data Plane Development Kit (DPDK) rapid packet processing mechanism, and feature high and stable computing performance. Equipped with high-performance NICs, the C3 ECSs provide high performance and stability, meeting enterprise-grade application requirements.

Scenarios

  • C4 ECSs: Websites and web applications, generalized databases and cache servers, and medium- and heavy-workload enterprise applications with strict requirements on computing and network performance

  • C3 ECSs: Small- and medium-scale databases, cache servers, and search clusters with high requirements on stability; enterprise-grade applications
